AUTOMOBILE TIRE.

Specification of Letters Patent. Pat911t6i May 25, 1915.

- Application filed July 10, 1912. Serial No. 708,582.

To all whom may concern Be it known that I, Tnrovn A. HALL, a subject of the King of Sweden, residing at Cleveland, in the State of'Ohio, have i11 vented certain new and useful Improve-- -turable, but yet resilient.

To carry out the object of my invention I employ a solid'trcad portion, preferably made 'outoi rubber and a cushion for said tread preferably pneumatic, and interposed a metal ring or hand between the said two elements. r

In the drawings which form partof this specification: Figurc'l is a side view of a Vehicle wheel equipped with my improved tire. Figf 2 is an enlarged cross sectionai view taken on a-line 2-2 in Fig. 1; and F1 3 is a similar view of a mod fied torm b X of my improved tire.

In the drawnnr 1 indicates the 'rellv now u l tlon of. a wheel, the out faces of which are provided with wear plates 'l'hewcar plates 2 contact with side plates or rings 5 ad accnt to theperiphery of which is se- 'cured a circularbed plate or band i, preferably metal, by means of machine screws 5. It will be seen inFig. 1 that the peripheral edges of the rings or plates 3 pl'OjOCt be yond the ring .4 to torin an annular scat 5" to receive; and hold tliotrca'd portion; which is referably made out of solid rubber. The

si' e plates or rings 3 are kept in contact with the wear plates 9, and in position upon the whcchby means of bolts 7,' which pass through the ears on the side plates and through ajaw 8 of a bracket 9 secured to the inner surface of the telly of the wheel.

1 The bolts? are adapted to move in the said jaw longitudinally thcrcot, but bear against the walls of the said jaws, whereby the tire and wheel are rotatably connected. During therotation of the wheel, under load, the

tire will slide upon the wear plates, the load being resisted by a cushioning device which comprises a rubber case or shoelO contain iug an inflatable tube 11. [Th case or shoe is maintained in position in the annular chamber 12 by means of the filling rings 13 which are p eferably hollow to reduce weight. The rings 13 fill the space between the side plates 3 and heading 1% of the case or shoe 1.0, whereby the cushioningelement is prevented from shifting transverselyof the chamber 12. vA. portion'ofthe wall-of ihe shoe 10 contacts with the inner surface of the side plates 3, while the periphery of the said shoe contacts with theunder surface ot'thc circular bod plate or hand i. The load upon the wheel is imparted to the cushioning device through the movableor sli lable casing which contains the cushioning device, and which consists of the side plates and attached bed-plate or band 4,;

"lhc tirc as illustratml in Fig. 3, is the same" i 75 as illustri'itcd in Fig.- 2, excepting that the solid tread is omitted, the band 15 forming the tread.

To prevent a static electricity from being generated I prefer to in'sert in the plates 3 and rings L and 15 any suitable anti-fri-ctional material 520, by which means the tire 10 is kept out of contact with the metal.

I claim as my invcntionz- In a vehicle wheel, in combination, a circola r tread portion; a concentric wheel portion within the tread portion,- a pneumatic tire between the two, a pair of circular pla tcs scoured at opposite sides to said tread portion and inclosing the tire and wheel portion and sliding" on the latter within the limitsof the resiliencyof the tire,-means securing theinner sel es of the side plates:

freely 'moviible within the wheel portion," clenchcr filling means bet-ween the side.

plates and the tire and resti g freely vupon the wheel portion, and inset wearing faces U in the side plates and the tread portion tangent to the tire at the'points of contact,

Signed at New York city in the countv of New York and State of New York this 3 day of July, 1912.
